Farnborough Air Show 2018 (35 minutes by rail to London) will be held in July.

Boeing 787 PITOT TUBES PROMPT NEW DIRE WARNING FROM THE FAA "Abrupt pilot control inputs in this condition could exceed the structural capability of the airplane."

"Abrupt pilot control inputs in this condition could exceed the structural capability of the airplane." FAA

Next time you are booked onto a Boeing 787 Dreamliner it might be a jolly good idea to print out and hand a copy of this new FAA directive to your Captain....

"We are issuing this AD to ensure that flightcrew avoid abrupt pilot control inputs in response to an unrealistic, sudden drop in displayed airspeed at high actual airspeed. Abrupt pilot control inputs in this condition could exceed the structural capability of the airplane."

The FAA also requires Boeing 787-8 and Boeing 787-9 operators to update the flight manual with the warning message:

AIRSPEED DROP

In the event of a sudden, unrealistic drop in indicated airspeed, do not apply large, abrupt control column inputs.

Fly the airplane with normal pitch and power settings.

If manual flight is needed, disconnect the autopilot prior to making manual flight control inputs.

787’s airspeed sensors, three separate devices called pitot tubes, are prone to some of the same problems that have plagued many other jetliner models over the years.

“Significant water ingestion or simultaneous icing” of two of the tubes can cause the displayed speed to drop sharply below the plane’s actual speed, according to the FAA, and such “erroneous low airspeed” readings can lead to dangerous commands by pilots.

A Boeing spokeswoman said the company fully supports the directive and has worked “closely with the FAA to monitor the fleet and take appropriate actions.”

SUMMARY: We are adopting a new airworthiness directive (AD) for all The Boeing Company Model 787-8 and 787-9 airplanes.

This AD requires revising the airplane flight manual (AFM) to instruct the flightcrew to avoid abrupt flight control inputs in response to sudden drops in airspeed, and to reinforce the need to disconnect the autopilot before making any manual flight control inputs.

This AD was prompted by reports indicating that in certain weather conditions with high moisture content or possible icing, erroneous low airspeed may be displayed to the flightcrew before detection and annunciation via engine-indicating and crew-alerting system (EICAS) messages.

We are issuing this AD to ensure that the flightcrew avoids abrupt pilot control inputs in response to an unrealistic, sudden drop in displayed airspeed at high actual airspeed.

Abrupt pilot control inputs in this condition could exceed the structural capability of the airplane.
